Sunday nights at this Old Town standby can be frustrating if you haven’t put in an order for Nana’s Sunday Dinner, a family-style feast of, say, delicious-looking fried chicken with mac and cheese and strawberry shortcake—none of it is offered on the à la carte menu. But you still can eat well. A Caesar salad made tableside is one of the best we’ve had. Our table fought over a gorgeous curl of butter-poached lobster with lobster ravioli. The Chesapeake seafood stew’s broth could have used more punch, but it was packed with fresh shrimp, clams, and mussels. And an over-the-top brownie sundae complete with rainbow sprinkles shone.
